Zero Width Unicode Standard (ZWUS)

Zero Width Unicode Steganography — hide text inside invisible characters.

npm install zwus

Usage

import zwus from 'zwus';

// Encode & decode strings
const hidden = zwus.encodeString("secret");
const revealed = zwus.decodeToString(hidden);
// "secret"

// Encode & decode number arrays
const encoded = zwus.encodeNumberArray([72, 101, 108]);
const decoded = zwus.decodeToNumberArray(encoded);
// [72, 101, 108]

Base

Higher base = shorter output, but more likely visible in some renderers.

zwus.encodeString("hi", 3)  // default, safest
zwus.encodeString("hi", 6)  // compact
zwus.encodeString("hi", 8)  // most compact

Decode must match the encode base:

zwus.decodeToString(encoded, 6)

Interop

Encoded output is byte-identical to the Rust crate, so you can encode in JS and decode in Rust or vice versa.
